I am looking at a set of edelbrock rpm heads. They come assembled at summit with springs. On edelbrocks website it says for use with hydraulic roller, but I have a solid roller 306b comp cam. As long as my cam does not exceed the lift of the spring rating on the heads will it matter if they are used with solid lroller vs hyd roller? The cost savings are great if I can get the eddy heads assembled with springs that work with my cam. Thanks
